Just spitballing a thought I had,not sure how it could work but for realisim and to try to make some use of the Patrol Routes feature for LE vehicles.
I know when I'm out on patrol , I tend to make a lot of traffic stops when I'm just riding around my beat. It would be nice to see about some type of self initiated traffic stops for units on patrol or in "Status 1" or unit specific traffic stop mission. I know there is a traffic stop operation "timed" mission but was just spitballing about how to make it a bit more real.
Not sure how the concept could be worked but it would be a very realistic addition to LE patrol cars.
